This invention relates to means for converting an ordinary single-decknarrow-ware or tape loom into a partial double-deck loom, in accordancewith the principles disclosed in the applicants prior Patent #1598230dated Feb. 21, 1933. The present invention relates to improvements inthe converting mechanism over that shown and described in the abovenoted patent.

The object of the present invention is to simplify the construction ofthe converting mechanism, whereby the conversion of a single-deck loominto a partial double-deck loom is greatly facilitated, by reducing thenumber of elements necessarily removed from the single-deck loom to bereplaced by the converting elements forming the subject of the presentinvention, which will be fully disclosed hereinafter, reference beinghad to the accompanying drawings, of which:

Fig. 11 is a transverse sectional elevation taken on the line 11--11,Fig. 7; and

Fig. 12 is a transverse sectional elevation taken on the line 12-12,Fig. '7.

In Figs. 1 to 6 of the accompanying drawings, the lay beam of anordinary single-deck fiyshuttle loom is illustrated at l. 2-2 indicatethe usual form of low shuttle guide brackets of a single-deck loom whichare secured to the lay beam 1 by screws 3, 3. Between each adja centpair of brackets 2 is normally located the reed comb 4, through whichthe warp ends of the strips of tape extend.

Secured to each of the brackets 2, by means of screws or bolts 5, 5 and6, 6, are shuttle guide blocks '7 and 8 respectively. Each pair of guideblocks 7 and 8, secured to one of the brackets 2, constitute a raceway 9for a shuttle 10 which carries the weft thread back and. forth acrossthe reed comb 4 in the open shed formed by the warp threads extendingthrough said reed comb.

In its travel across the reed comb 4, in each instance, the shuttle 10is passed from the raceway 9 of one of the brackets 2 to the raceway 9of the next adjacent bracket 2, reciprocation of the shuttles 10 in thepresent instance being efl0 fected in the same manner as described inthe above mentioned prior patent.

The present invention primarily consists in substituting for any singleone of the guide supporting brackets 2, or for any desired group of 76immediately adjacent brackets 2, in predetermined places along the layof the loom, an auxiliary bracket, or a series thereof, such asindicated at 20 in Figs. 1 to 5 inclusive.

Each of the high auxiliary double-deck 80 brackets 20 is provided with alower securing tongue portion 21, which corresponds in general shape andcharacter to the securing tongue 11 of each of the low singledeckbrackets 2, the tongues 21 of the auxiliary brackets 20 being drilled inthe same manner as the tongues 11 of the single-deck brackets 2 toreceive the screws 3, 3 for securing the auxiliary bracket 20 in exactlythe same position on the lay beam 1 as that as formerly occupied by thesingle-deck bracket 2 which has been removed and replaced by theauxiliary bracket 20.

Each of the auxiliary brackets 20 comprises a body portion 22 which isdrilled and tapped in the same manner as each of the lowsingle-deckbrackets 2, for receiving the screws 5 and 6 by which the guide blocks 7and 8 of the auxiliary bracket are secured to the auxiliary bracket inthe same position, with respect to the guide blocks on the low brackets2, 2 at opposite sides respectively of the auxiliary bracket, as theseguide blocks occupied when carried by the removed single-deck bracket 2.

Extending vertically from the body section 22 of the auxiliary bracket20 is a pair of laterally spaced arms 23, 23, between which is disposedan upper deck reed comb 4a. The lower end of the reed comb 4c is seatedin a cavity 25, which is formed between a cross fin 26, that extendsbetween and is integrally connected at its opposite ends to the sidearms 23, 23 respectively, and the rear face of the upper guide block 7,which is carried by the body portion 22 of the bracket 20.

The upper end of the upper deck reed comb 4a is located in a slot 25awhich is formed between a back cross fin 2'7 and a front cross fin 28integrally formed at their opposite ends with the upper ends of the sidearms 23, 23 respectively.

Formed integral with and extending laterally in opposite directions fromthe side arms 23, 23 are upper wings 30, 30 and lower wings 31, 31.

Secured at their outer ends to the upper wings 30, 30 by screws 5a, 5a,and at their inner ends to the side arms 23, 23 of the bracket 20 byscrews or bolts 51), 5b are upper shuttle guide blocks 7a, 7a, the saidinner ends of which are disposed adjacent to and at opposite sides ofthe upper deck reed comb 4a.

Secured at their outer ends to the lower wings 31, 31 by screws 6a, 6a,are lower shuttle guide blocks 8a, 3a, the inner ends of said guideblocks being secured to the side arms 23, 23 of the bracket 20 by screwsor bolts 6b, 6b.

The guide blocks Fa-8a at the opposite sides of the upper deck reed comb4a provide raceways 9a, 9a for the reception of a shuttle 10a operablefrom one to the other of said guideways in the same general manner andby the same general mechanism as disclosed in the said copendingapplication.

In the same manner as disclosed in the abovementioned prior patent theupper ends of the reed combs 4, 4 of the single lower deck aremaintained in position, transversely of the lay 1, by

front and rear bars and 61 respectively, and laterally or longitudinallyof the lay by and be tween pads 64, 64 formed on the opposite sides ofeach of the single-deck brackets 2, the bars "60 and 61 being secured tosaid brackets 2 by screws 62.

In the form of the invention shown in the said prior patent, in order toprovide raceways for a single shuttle in the upper or auxiliary deck, itwas necessary to remove three of the lower deck brackets which had to bereplaced by three of the auxiliary brackets.

In the form of auxiliary bracket shown in the present application, inorder toprovide the guideways or raceways for a single shuttle in theupper or auxiliary deck, it is necessary to remove but one of the lowerdeck brackets and to substitute one of the auxiliary brackets therefor.

The reed comb securing bars 60 and 61 are cut I away adjacent the twolower deck brackets 2, 2-

respectively disposed at opposite side of the lower deck bracket to beremoved and replaced by an auxiliary bracket 20, and in order tomaintain the rigidity afforded by the bars 60 and 61 the auxiliarybracket 20 is provided with laterally extending lugs 65, 65, disposed inline with the bars 60 and 61, which overlap the ends of the bar 61 atthe rear of the lower deck brackets 2, 2 on either side thereof. Thelugs 65, 65 are secured to the said adjacently disposed lower brackets2, and to the bars 60 and 61, by screws 66 which pass completely throughthe bars 60 and 61 and the brackets 2, 2. The screws 66 are threadedinto the lateral lugs 65, 65 of the auxilir ary bracket 20.

removed. However, this is not essential in that the lower wings 31, 31may be made shorter to fit within the space between the pads 64a, 64a,making it unnecessary to remove any portion of the adjacently disposedlower brackets 2, 2.

The form of the invention illustrated in Figs. 8 to 12 inclusiveconcerns the application of the present invention to looms of therack-shuttle type. In that form of the invention shown in Figs. 3 to 12,a rackshuttle loom of the type wherein the shuttles oscillate in arcuateguideways has been shown. In this type of loom a series of low brackets102, 102 are secured to the lay 101, in the same manner as the brackets2, 2 of the flyshuttle loom of the type disclosed in Figs. 1 to 6inclusive, to provide a single deck in which operates a series ofoscillating shuttles 110. Between each adjacently disposed pair ofbrackets 102 is a reed comb 104 at the opposite sides of which is aguide block 103 in which is formed a pair of intersecting arcuateT-shaped grooves forming guideways 109 for the reception of the shuttles110. In this case the shuttles 110 are provided with segmental gearracks 140 which are arranged to be engaged by the teeth of pinions 141rotatably mounted in cavities 142 formed in each of the guide blocks108, which are secured to the brackets 102 respectively. The teeth ofall the pinions 141 engage the teeth of a gear rack 143, which isslidably mounted in the lay 101 for reciprocation by mechanism similarto that shown and disclosed in the above mentioned application.

In order to convert this type of loom into an auxiliary decked loom, anyone of the brackets 102 may be removed and replaced by an auxiliarybracket 120, in the same general manner as above described with respectto the replacement. of a bracket 2 by an auxiliary bracket 20 in theflyshuttle type of loom shown in Figs. 1 to 6 inelusive.

Each bracket 120 is provided with a tongue 121 corresponding to thetongue 111 of each of the brackets 102. The tongues 111 and 121 arecorrespondingly drilled to receive the screws or bolts 103 by which thebrackets are secured to the lay 101.

Each auxiliary bracket 120 comprises a body portion 122 to which issecured one of the lower deck shuttle guide blocks 108, in the sameposition as formerly occupied when such block was carried by the removedlower bracket 101, that has been replaced by the auxiliary bracket 120.

Each auxiliary bracket 120. comprises side arms 123, 123 which areprovided with laterally extending wings 130 and 131. The side arms 123,123 are connected by lower fins 126, 126 between which is provided acavity 125, for the reception of the lower end of the upper deck reedcomb 104a. The reed comb 104d is carried by the bracket 120 betweenlaterally spaced guide block sections 108a, 108a respectively carried byand secured to the arms 123, 123 and the wings 130 and 131 of thebracket 120. The upper end of the reed comb 104a is positioned in a slotor cavity 125a formed between a rear fin 127, which integrally connectsthe upper ends of the arms 123, 123 and the rear face of an upper bridgeportion 128 that integrally connects the upper ends of the guide blocksections 108a, 108a, and provides in the block a slot 129 in line withthe reed comb 104a.

In order to oscillate the shuttle 110a in the guideways 109a formedinthe block sections 108a, 108a, a pair of gears 141a are rotatablymounted in the said blocks 108a, 108a respectively at opposite sides ofthe slot 129 for engagement with the rack teeth in the lower surface ofthe shuttle 110a. The gears 141a, l ila mesh with the teeth of an upperdeck rack 143a which moves in unison with the lower rack 143 and whichmay be connected to the rack 143 in any suitable manner to bereciprocated with the rack 143 by the same mechanism which reciprocatesthe said rack 143. The rack 1 13a is slidably mounted in grooves 114formed in the upper ends of the guide blocks 108 carried by the lowerbrackets 102 respectively.

From the above, it will be noted that the present invention isapplicable to the conversion of single-deck looms of either thefly-shuttle type, such as that shown in Figs. 1 to 6, or the racktypeloom shown in Figs. '7 to 12, with equal facility in either case, bymerely removing one of the lower deck brackets and replacing suchbracket with one of the interchangeable auxiliary brackets.

It will be noted that the lower wings 31, 31 in that form of highbracket shown in Figs. 1 to 6 inclusive include cavities 25b, 25b forthe reception of the upper ends of the reed combs 4, 4 of the lower deckwhich are respectively disposed between the high bracket and the two lowbrackets respectively disposed at opposite sides of said high bracket.
